An Ancient Greek Philosopher Was Exiled for Claiming the Moon Was a Rock, Not a God

Close to the north pole of the moon lies the crater Anaxagoras, named for a Greek philosopher who lived in the fifth century B.C. The eponym is fitting, as Anaxagoras the man was one of the first people in history to suggest the moon was a rocky body, not all too dissimilar from Earth. Streaks of material thrown out during the impact that formed the crater extend 560 miles southward to the rim of another crater, this one named for Plato.
Like Plato, Anaxagoras the scholar did most of his work in Athens, but the similarities between the two men stop there. Influenced strongly by the Pythagoreans, Plato posited a mystical universe based on sacred geometric forms, including perfectly circular orbits. Plato eschewed observation and experimentation, preferring to pursue a pure knowledge he believed was innate in all humans. But Anaxagoras, who died around the time Plato was born, had a knack for astronomy, an area of study that requires careful observational and calculation to unlock the mysteries of the universe.
